A check for GERD: Ph testing can check your esophagus for exposure to substances regurgitated from the stomach-- for acid (such as bravo ph capsule implanted on your esophagus) as well as non-acid reflux (ph impedance testing). The test correlates your symptoms in real-time with what comes up into your esophagus & throat. Ph testing also has utility in assessing the efficacy of acid-blocker drugs.
